JOHN PETTINGER, OF SANTA BARBARA, CALIFORNIA.

VEHICLE-WHEEL BEARING.

SPECIFICATION forming part of Letters Patent No. 556,640, dated March 17, 1896.

Application filed May 17, 1895. Serial No. 549,681. (No model.)

To all whom it may concern.-

Be it knouni that I, J onx PETTINGER, of

Santa Barbara, in the county of Santa Barbara and State of California, have invented and details and combinations of the same,

as will. be fully described hereinafter and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, of which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is alike view of a modified form of dust-cap.

The hub A of the vehicle-wheel is provided with a hub-box 13, made cylindrical at its inner end and solid near the forward end, with a spindle l3 projecting from the solid end rearwardly through the cylindrical part, as plainly illustrated in the drawings. This spindle B extends into the tubular end G of an axle O, and the end of the said spindle is reduced, as at C to engage a bearing D secured in the tubular part of the said axle G. The outer end of the spindle and that which is opposite the reduced end 0 is formed with an enlargement X, which is received in a countor-enlargement Y formed at the adjacent end of the axle.

The spindle B is preferably about eighteen inches long, so as to aiford a good connection between the spindle and the axle. A collar or nut E screws on the inner end of the hub-box 13, to abut with its inner end on a shoulder formed by an enlargement C shrunk or otherwise secured to the end of the axle. The inner end of the hub-box Bis preferably provided with a flange 13 engaging a shoulder A formed in the inner recessed end of the hub A. If desired, an axle-stock F may be attached to the axle C by a clip G in the usual manner.

The forward solid end of the hub-box B is provided with the usual threaded reduced portion B, on which screws a nut G abutting on a collar G resting ona shoulder A in the outer recessed end of the hub A. A dustcap H is secured on the outer end of the hub A to prevent dust from passing to the hubbox, and a similar dust-cap H is secured to the axle O to extend with its flange over the collar E, as shown in Fig. 2.

It will be seen that a considerable quantity of lubricant can be passed into the space between the spindle B and the tubular end O of the axle, so that the wheel can be run for a long time without requiring a reapplication of the lubricant.

It will be seen that by the arrangement described the friction of the bearing parts is reduced to a minimum, and the wheel-hub A, by reason of the long spindle B, will always maintain a proper relation to the axle C, so that the wheel will run perfectly at all times, and consequently wabbling of the wheel is prevented.

It will further be seen that by the arrangement described the axles can be very easily set and are less liable to get out of the true set.

' Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A vehicle-bearin g, comprisinga hub having a hub-box therein, the same being hollow, a centrally-located spindle projecting from the outer end of the hub-box inwardly and beyond the hub and having at its inner extrem- 8 5 ity a reduced portion and having an enlargement at its outer extremity, a hollow axle fitting in the hub-box and receiving the spindle and having at its inner portion a reduced recess receiving the inner end of the spindle, go the axle also having a counter-enlargement at its outer extremity receiving the enlargement at the outer portion of the axle, and an exteriorly-threaded nut embracing the hollow axle and screwing into the inner end of the hub- 5 box, substantially as described.

JOHN PETTINGER.
